This is the general term for a group of hands on soft tissue therapies that focus on the muscles (myo) and fascia (fascial) of the body. Most of these therapies tend to focus strongly on the fascia component and it's relationship to the muscles rather than the muscles directly. For a basic understanding of these therapies you can think of the muscles like meat and the fascia like the thin white membrane around it. Another useful analogy is to think of fascia like shrink wrap because it sticks to and surrounds muscle.
